// Experimental: exercises the end-to-end GitHub (hydro) telemetry forwarding
// path. The runtime forwards per-session telemetry to opted-in connections via
// the `gitHubTelemetry.event` JSON-RPC *notification*; the SDK opts in
// automatically whenever an `onGitHubTelemetry` handler is registered. Creating
// a session emits an early `session.start` hydro event, so no model round-trip
// (and therefore no recorded CAPI exchange) is needed to observe forwarding.
